Solution Overview

Problem

Generating realistic virtual races requires significant computational resources, whether through resource-intensive computer animations or limited real-world footage, which affects user experience and efficiency.

Innovation Solution

A method that combines pre-recorded real-world race footage with a digitally modified finish clip to create a virtual race outcome, reducing the need for intensive computer animation by using randomly generated outcomes to alter real-world footage in real-time or from pre-generated archives.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If computer-generated animation is used to produce virtual race, then the race result can be任意 set, but the computational resources and processing power required are significant

Engineering Contradiction:

Improverace outcome flexibilityVSAvoidcomputational resources

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent combines real-world race footage with digitally modified finish clips to create virtual races. This merging approach allows the system to use existing realistic video content while only animating the critical finish portion, thereby reducing overall computational requirements while maintaining outcome flexibility.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent uses copies of real-world race footage as the basis for virtual races. By copying and reusing authentic race video content, the system avoids generating entire race sequences from scratch, significantly reducing computational resources while preserving realism and allowing arbitrary finish outcomes through clip selection and modification.

Inventive Principle:

Principle #26Copying

2Reliability

If computer animation is used to improve realism of virtual race, then the user experience is enhanced, but the computer processing power required is significant and makes implementation difficult

Engineering Contradiction:

ImproverealismVSAvoidprocessing requirements

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the race video into distinct portions: authentic real-world footage showing the race progression, and a separately produced digital finish clip showing the customized outcome. This segmentation allows the system to maintain high realism in the majority of the video while using simplified animation only for the critical finish portion, reducing overall processing complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary action by pre-recording and archiving real-world race footage before the virtual race event. This advance preparation allows the system to simply select and combine pre-existing realistic video content with a finish clip, rather than generating entire race sequences in real-time, thereby reducing processing requirements during virtual race execution.

Inventive Principle:

Principle #10Preliminary action

3Use of energy by moving object

If real-world footage is used to produce virtual race, then the scope of possible results is limited, but the computational resources required are reduced

Engineering Contradiction:

Improvecomputational resourcesVSAvoidrace outcome options

Core Design Contradiction:

Use of energy by moving objectVSAdaptability or versatility

Solution Approach 1:

The patent extracts only the critical finish portion from the real-world footage and replaces it with a digitally generated finish clip that reflects the desired virtual race outcome. This extraction approach allows the system to maintain the authenticity and resource efficiency of real-world footage while gaining the flexibility to produce any desired finish result through the modified clip.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A computer implemented method (100; 300) for producing video data (200) of a virtual race for display at computing device. The method comprising: determining (102; 302) a randomly generated outcome of the virtual race; obtaining (104; 304) virtual race video data (200) which is representative of the virtual race and which corresponds to the randomly generated outcome. The virtual race video data comprises: one or more race video clips (202) recorded from a real-world race occurring prior to initiation of the virtual race at the computing device; and a virtual finish video clip (204) appended to the one or more race video clips (202) , wherein the virtual finish video clip (204) is a modified real-world finish clip (204') recorded from the, or another, real-world race occurring prior to the initiation of the virtual race, the real-world finish clip (204') having been modified to represent a race result that corresponds to the outcome of the virtual race. The method further comprises sending (106; 306) the virtual race video data (200) to a display of the computing device. An apparatus for carrying out the method is also disclosed.
